Graph A: Velocity of a falling object (Linear Function) A ball is dropped from rest near the surface of the earth. The force of gravity is the only force acting on the falling ball. The velocity (m/s) of the falling ball has been measured at different times (3). The results are shown in Table 1 Table 1. The velocity of the ball dropped from rest measured at different times Time :(s) Velocity v (m/s) 0.42 4.20 0.56 5.60 0.78 7.80 1.04 10.40 1.14 11.40 1.30 13.00 1.44 14.40 1.62 16.20 (a) Set up an empirical equation for the velocity of the ball at different times. This equation should use the numerical values of the constants and indicate their units.
